Hi I have an off-road buggy running xr3i engine, keys for ignition lost and can't seem to find a like for like barrel with key to replace so I guess the next port of call is to hotwire. I presume the red is the battery feed, not sure on the rest and don't want to just experiment and end up burning out wiring.. Local Halfords don't have a Haynes for escorts so no joy there and not managed to find anything yet on google..
Any help appreciated, Kev
